Low mount winch in a high mount winch bar

[canuck]

99% absolutely mate. It's the other way round that can be a problem sometimes and needs a mod. You should have no trouble at all.

I can tell you that a high mount winch will not fit into a stock Nissan winch bar without making up an adapter plate to move the winch forward. As MudRunner says, the other way a round should be no problem.
